REPLAY is an audiovisual content management platform developed at ETH Zurich.
Background
Conceived as the future Multimedia Portal for ETH Zurich within the framework of the 2006–2009 ICT strategy, the system was named "REPLAY" in 2007. It streamlines the entire process of handling ETH Zurich’s audiovisual materials, from creation through to distribution.
Application area
REPLAY specializes in near-automated processing of substantial quantities of lecture recordings (exceeding 150 weekly) and provides a comprehensive management solution for various video assets, including films and digitized content. Its user base includes academic institutions, museums, and enterprises that oversee large audiovisual collections.
Workflow
The platform oversees the complete audiovisual content lifecycle: In lecture halls, audio, video, and VGA signals are captured automatically by Linux-based Playmobil hardware. These inputs are combined with metadata and processed within REPLAY’s backend system. Additional video files can be added through an inbox feature.
The resulting packages undergo:
- archiving,
- indexing (utilizing Optical Character Recognition to extract slide text),
- encoding according to predefined configurations,
- distribution via multiple channels such as RSS, streaming services, and downloads.
One of the distribution interfaces is Interplay, which offers an interactive environment for video consumption.
Qualities
Constructed using Java, REPLAY is an open source, standards-compliant, modular solution designed for deployment on either standalone or distributed infrastructures.
License
The software is released under the GNU LGPL version 2 open source license.
Development
By March 2009, development reached version 0.7; however, the project concluded and support was discontinued by the end of 2009. The core technology behind REPLAY has since been integrated into the Opencast Matterhorn initiative.
